What is DeepForest?¶
DeepForest is a python package for training and predicting individual tree crowns from airborne RGB imagery. DeepForest comes with a prebuilt model trained on data from the National Ecological Observation Network. Users can extend this model by annotating and training custom models.

How does it work?¶
DeepForest uses deep learning object detection networks to predict bounding boxes corresponding to individual trees in RGB imagery. DeepForest is built on a fork of the keras-retinanet package and designed to make training models for tree detection simpler.
The simplest use case is to download the prebuilt model and apply it to a single image.
from deepforest import deepforest import matplotlib.pyplot as plt model = deepforest.deepforest() model.use_release() img=model.predict_image(<path_to_image>,return_plot=True)
For a quick example of model performance on sample images, see our demo shiny app. Please note that the model continues to improve and the app model may not reflect results from the current release.
Remote sensing can transform the speed, scale, and cost of biodiversity and forestry surveys. Data acquisition currently outpaces the ability to identify individual organisms in high resolution imagery. Individual crown delineation has been a long-standing challenge in remote sensing and available algorithms produce mixed results. DeepForest is the first open source implementation of a deep learning model for crown detection. Deep learning has made enormous strides in a range of computer vision tasks but requires significant amounts of training data. By including a trained model, we hope to simplify the process of retraining deep learning models for a range of forests, sensors, and spatial resolutions.
All issues can be submitted to the github repo. We look forward to hearing about the performance of the prebuilt and custom models. We encourage all users to submit a sample image issue, regardless of performance, to the image gallery. We want to hear from you!
